US Classification:

Abstract:

A dent removal system is provided having a portable vacuum chamber head and a shaper vacuum roller coupled to a vacuum source. The vacuum chamber head has a center see-through window for aligning the head over a dented work surface, a template of desired surface shape and a matrix of closely-spaced standoff pins to communicate the template shape to the work surface while allowing passage of vacuum to the dent. A method is provided for removing dents in sheet metal surfaces using the dent removal system. The vacuum chamber head is positioned over the dented work surface and sealed. The work surface is excited with vibrational energy. Within the vacuum chamber head, force is applied to the template face to hold the template in fixed relation to the work surface. The template shape is transmitted to the work surface via the matrix of standoff pins. Vacuum is applied to the chamber head, through the standoff pin matrix to the work surface sucking the dent out of the work surface and forcing the work surface into contact with the standoff pins.
